feat: generate a random seed if none given

[WereCatf]

Currently the UI defaults to "31337" for the seed value but the code causes an exception if there is no value set for seed. This commit simply generates a new seed and updates the UI accordingly in that case, preventing the exception.

I think if you open demo_gradio.py in a text editor and change seed to '-1' i think that is the same thing. However you can't see what the random number is, so maybe your approach is better

As far as I understand, it's not the same thing:

Negative inputs are remapped to positive values with the formula 0xffff_ffff_ffff_ffff + seed.

nothing to do with the pull request? entirely irrelivant? its a mod that has random seed generation done perfectly and many other features. considering pull requests have not been processed in a while, i am offering people a mod that does them all and in a better way..

@chuckkay I don't care, it's not relevant to this pull request. Go spam someone else.

@WereCatf, I suggest you to apply this change also on demo_gradio_f1.py to make the code consistent.
